  - 2★ 2026-07-02, sapphire: there is no version 7 which exists according to changelog github.com/react/react/blob/main/packages/react-devtools/CHANGELOG.md\#react-devtools-changelog does not work in next.js 16
  - 2★ 2026-01-18, Firefox user 18503250: It worked well but hasn't been updated in over a year. The app breaks with the latest React/Next.js libraries due to a bug with params and searchParams in Firefox. There is last 7.1 version in Chrome that works fine. Is Firefox still supported?
  - 1★ 2025-07-16, Niraj Kumar: Why this extension in taking clipboard access. I think its a security issue. I have removed this extension
